Ilan Guttman

Biography

Ilan Guttman joined New York University Stern School of Business in July 2013. Professor Guttman teaches courses at the graduate and doctoral levels and he is the director of the accounting PhD program.

Professor Guttman's primary research interest lies in the application of economics of information in capital market settings. His recent research focuses on disclosure decisions by information holders (managers, financial analysts and others) and the market reaction to these disclosures. Some of the issues Professor Guttman has been studying include the nature of manipulation of disclosure by interested parties when disclosure is mandatory (such as in earnings management) and when it is voluntary; how managers' ability to manipulate reported earnings affects managers' optimal contracts; the interdependencies between disclosure, both mandatory and voluntary, and real decisions (e.g., investment and dividend decisions); the implications of studying a dynamic multi-period setting, rather than a single period setting, on voluntary disclosure decisions and earnings management decisions; debt contracting, analysts' optimal timing for issuing forecasts; and analysts' choice of optimal bias in their forecast.

Professor Guttman's work has been published in The Accounting Review, The American Economic Review, the Review of Financial Studies, the Journal of Financial Economics, the Journal of Accounting Research, the Review of Financial Studies and in Management Science.

Prior to joining NYU Stern, Professor Guttman served on the faculty of Stanford Graduate School of Business where he taught M.B.A. and Ph.D. classes.

Professor Guttman earned his B.A. in Economics, B.Sc. in Computer Science, M.A. in Economics and Business Administration, and Ph.D. in Economics, all from the Hebrew University of Jerusalem where he also taught microeconomics, finance and macroeconomics.
